Clinical Trial Summary

36 participants who have mild crowding from the Orthodontic Department at University of Damascus Dental School will be randomly assigned into two groups. 1. In the experimental group, patients will be treated using single aligner appliance in order to align their crowding teeth. 2. Control group will undergo typical orthodontic treatment using an MBT-prescription of metallic brackets.

Description:

Most adult patients do not prefer traditional fixed appliances for aesthetic reasons, long treatment duration, and relatively difficult oral care. The current study came in order to evaluate the Efficiency of a new single aligner appliance that is both aesthetic and economical.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Duration of Alignment	The time required in days will be calculated from the beginning of treatment till the end of the alignment stage.	The assessment is based on calculating days from the beginning of treatment till the end of the alignment stage which is expected to happen within 4 to 6 months
Primary	Change in Little's Index of Irregularity	The irregularity of the lower incisors is calculated by measuring the amount of deviations of the anatomic contact points between the six anterior teeth in the horizontal direction in mm, since the sum of these measurements represents the value of the index (Little, 1975). When the sum of these deviations is less than 3 mm, this indicates that the teeth are slightly crowded. When the sum is greater than 10 mm, this indicated very severe crowding.; The ordinary orthodontic treatment aims to keep this Index less than 1 mm at the end of treatment.	T0: immediately before the start of orthodontic treatment; T1: after one month; T2: after two months; T3: after three months; T4: after four months; T5: at the end of the alignment stage (which is expected to occur within 4 to 6 months
Primary	Change in Lower Incisors Inclination	The angle between the long axis of the lower Incisors and the mandible plane (Go-Me) will be measured using Cephalometric x ray.	immediately before the start of orthodontic treatment; T1: at the end of the alignment stage which is expected to happen within 4 to 6 months
